@lewlepton heh, that too. Loads of people here wear it under their chins.
@welshpixie its a fashion accessory... to hide the underside of your chin?
My wife got one for when we have to go food shopping. She has mastered the 'pointed look' to shame people into adjusting theirs properly.
@welshpixie people here need a 'it goes over your face' mask. because WOW they dont know how to wear them
